Can you buy a car with a credit card? If you’ve been in this miles and points world for more than a few minutes, you might have found yourself wondering how to go about earning miles on a car purchase. I recently found myself in the market for a car, and that prompted me to figure out how to maximize my mileage.
A little background
When I was in my late 20’s, I won a big poker tournament that I’d paid $15 to enter; with part of my windfall, I bought my dream car: a 1996 BMW Z3.
I drove it for six months and then sold it for a small profit. When I sold it, I said that I’d driven my dream car and could spend the rest of my life driving whatever is cheap and reliable. For about the past 7 years, that’s meant a Toyota Yaris that we bought used on eBay for $5500.
Forty miles per gallon on the highway and nothing but regular maintenance in cost has treated us well. But we recently added to the family and realized we were going to need more space. We decided to upgrade to either a new or late model SUV. As this would be one of the largest purchases we’ve ever made, I had miles on my mind.
Having spent years planning for the start of a family, we had saved up the cash to pay outright for the car we wanted. That’s a key piece of the puzzle in earning miles for a car purchase: if you’re going to use a credit card, you have to be prepared to pay it off. If you’ll be paying credit card interest, there are no miles in the world that are worthwhile. With the cash in hand to pay for the car, I went about finding ways to earn miles for the purchase of a car.
Method 1: Amex Auto Purchasing Program
Having Googled how to earn miles for a car purchase, I’d long ago read Richard Kerr’s piece at The Points Guy. Richard had bought a new car and paid in full on his Amex Platinum card. It’s a great story that’s worth a read — but ultimately, it was a YMMV (your mileage may vary) situation.
However, a piece of that story that stuck out was the Amex Auto Purchasing program. I’d seen this advertised under the list of benefits on my SPG credit card before (but I’d mostly ignored it).
Clicking through to learn more, it prompts you to visit amexnetwork.com/auto, which just brings you to a Amex-branded version of TrueCar.
If you’re not familiar with TrueCar, the one sentence explanation is that it’s a site that shows you the averages of true prices that others in your area have paid and shows you pre-negotiated prices with a number of dealers.
The Amex-branded version works exactly the same as TrueCar.com: You put in the make, model, and your zip code. ]If you want to view actual pricing on local inventory, you’ll have to enter your name, address, email, and phone number. I did this many times. Pro tip: don’t use your real phone number. I used a Google Voice number once — and within about 90 seconds of hitting submit, my phone started ringing. For the purposes of shopping around, you could really use any name, address, and phone number you want as long as you use an email address you can access. You’ll then see some local vehicles that may or may not match what you’re looking for in terms of options. More importantly, you’ll receive emails instantly or within a few hours from local dealers who participate in the program.
At the bottom of the email you receive from each dealer, there is contact info. There is also a “benefits” section — this is where it says how much the dealer will accept on any American Express card. Most dealers take between $2,000-$5,000 on an Amex. See the image below — this dealer takes any Amex up to $5K:
But that’s not very exciting. After all, you’re not going to find a new car in the US for $5K. The good news is that there actually are some dealers that accept more. While they certainly weren’t the norm, I did find a few dealers where it said right in the email that they would accept any American Express Card for up to the full purchase price:
During my search with the Amex Auto Purchasing program, I was only searching for one type of vehicle and I found a few dealerships willing to take the full purchase price on a card. None of those dealers were near me. I had cast a wide net since I was willing to fly somewhere and pick up the car if the deal had been right. That required filling out the Amex Auto Purchasing form again and again with addresses in different zip codes. But I can confirm that when Amex says some dealers take up to the full purchase price on an Amex, those dealers do exist.
Advantages to the Amex Auto Purchasing Program:
- It’s an easy process. This would save time if you’re busy and don’t have the time to dedicate to shopping and negotiating.
- The dealers come to you. You’ll get a billion emails — both initially and then daily from sales reps hoping to help you make a decision. I suggest using a throwaway email account, because the emails don’t stop no matter how many times you don’t respond and how many months go by. The good news is that you can shop in your PJs.
- You might get a better deal than you otherwise would have if you’re a bad negotiator
- You can potentially earn a decent haul of miles/points.
A note on that last bullet point: an auto purchase could potentially be good for hitting a large minimum spend. For example, the welcome offer on the SPG Business card recently increased to match its all-time high (see the current offer here). If you’d otherwise have trouble meeting the minimum spend, this could be an easy way to do it and earn both points on the cost of the car and a big bonus (provided of course that you have a high enough limit to charge the cost of the car. I’d suggest a call to Amex to let them know what you’re planning before making a huge purchase on a brand new card). While the best public offer on the Business Platinum Card is currently 75K points after a total of $20K spend in the first 3 months, I received a targeted offer a few years ago to earn a welcome offer of 150K points after $20K spend in 3 months. Keep in mind that this card earns 1.5x on purchases of $5,000 or more. There are a number of other possibilities as well (see below for some examples).
Disadvantages of the Amex Auto Purchasing Program:
- You might be able to negotiate a better price without the program (it may be possible to negotiate the Amex prices as well)
- Dealers probably won’t negotiate much though if you’re paying in full on a credit card
- My guess is you’re paying at least an approximate 3% markup if you’re paying the full purchase price (so the dealer can recoup swipe fees)
- If you’re looking at a dealer that only takes $2K-$5K, you probably don’t need the program — many dealers will take a few thousand as a down payment on any credit card.
Example miles for a $30K car:
As a point of comparison, I’ll look at how many miles you could earn on a $30K car with each method. With the Amex Auto purchasing program, here are a few options you could consider:
- The Blue Business Plus. Earn 2x if you’re within your first $50K in purchases.
- Potential total = 60K Membership Rewards points (+10K if you’re signing up right now with a referral link — see: New 10K offer on 2x everywhere card).
- Everyday Preferred. Earn 1.5x if you do at least 30 transactions in the month.
- Potential total = 45K Membership Rewards (plus 20K with the current Best Offer)
- Targeted Business Platinum offer. If you received an offer like I did (expired at the moment, but occasionally available via targeted mailer):
- Potential total = 195K Membership Rewards points (150K + 45K)
Method 2: Manufactured Spending
We maintain a Manufactured Spending Complete Guide with tips for how to increase your credit card spend. One way some people do that is by purchasing PIN-enabled Visa or Mastercard gift cards and then using those cards to purchase money orders. This method is highly variable depending on location: many places that sell gift cards may not accept a credit card as payment; some places that sell money orders will not accept debit cards as payment; some card issuers may not award signup bonuses, regular spending points or cash back on gift card purchases (See: Amex fires another shot in their war on gaming, Alliant paying 0% cash back at Giftcards.com).
However, let’s say you live in an area where this is possible. In that case, you could use credit cards to indirectly pay for a car (or any purchase of course).
Let’s say for example that you pay an activation fee of $5 per $500 gift card and a money order fee of $1 per $1,000 money order (YMMV — this could be higher or lower depending on your area, what kind of cards you buy, promotions, etc).
The total cost for a $30,000 vehicle would look like this:
- 60 x $5 (activation fees on $500 gift cards) = $300
- 30 x $1 (money order fee for each $1K) = $30
- Time & gas = YMMV…this is going to involve multiple trips/stops
In total, you’ll pay $330 plus time and gas on top of the purchase price of the car in order to use this technique.
Advantages of Manufactured Spending technique
- Negotiate the price of the car on your own – maybe get a better deal
- Might be able to skip depositing the money orders and pay the dealer with them directly
- Earn a ton of points by spreading this over multiple signup bonuses
Arguably the best thing going for this technique is the last bullet point. With most signup bonuses requiring around $3,000 in spend, you could potentially knock out somewhere around 10 signup bonuses with a $30K vehicle purchase. Of course, that requires opening ten cards. That might require time and certainly requires planning. Of course, if you have the money saved up to purchase your vehicle, you could take your time and do this over the course of months or longer.
Disadvantages of Manufactured Spending technique
- If you pay thirty thousand dollars in $1K money orders, you might need to convince a car dealer that you’re not a drug dealer
- This technique potentially requires a lot of time: time spent buying gift cards, time spend liquidating, time spent earning signup bonuses if you’re spreading out applications, etc
- There’s much higher risk. Amex has been known to deny signup bonuses based on gift card purchases. There’s the potential for triggering Amex Financial Review or Chase Financial Review based on sudden large gift card purchases.
- Requires lots of organization
This certainly isn’t an impossible technique. In fact, I did consider this method. It certainly could be well worth the trouble if you’re able to knock out some good offers. But this technique certainly isn’t for everyone and isn’t as safe and simple as the Amex Auto Purchasing Program and technique #3….
Example miles for a $30K car:
I think the most realistic way to figure this is based on earning the maximum number of signup bonuses. Of course, there are tons of different signup bonuses on our Best Credit Card Offers page. You could mix and match a variety of cash back offers, transferable points offers, hotel points offers, etc. However, since this post is about earning miles for a car purchase, I decided to just go to our Top 10+ Airline Credit Card Offers page.
I went through the list, excluding Amex cards (since they are known to deny the signup bonus based on gift card spend) and I added up the signup bonuses available on the other top airline card offers until I got to $30K in required spend. I didn’t want to go over $30K in required spend — though as shown above, your actual cost via this method would be $30,330 plus gas.
There are two airline credit cards in the top 20 that currently offer signup bonuses after first purchase (The Avianca Vuela Visa and the Barclaycard Aviator). I got to $29K in required spend on eight other cards and assumed you’d split the final $1,330 spend over those two bonus-after-first-purchase cards. Assuming no bonus category spend (i.e. figuring 1x on the $30K), you would have a total of 590,000 airline miles if you were able to open the cards with the best non-Amex airline card offers that add up to $30K. We value most airline miles at 1.4 cents each (read more about why: Airline Miles are worth 1.4 cents each. A simplified approach to Reasonable Redemption Values.), making that pile of miles worth a reasonable value of more than $8,000 (though you could certainly get more value).
I didn’t spend too much time considering realistic logistics; for example, there might have been more than 5 Chase cards that are subject to 5/24 in that list. Real-world results may vary a bit — suffice it to say that you would have a lot of miles with this technique. But it carries risk of shutdowns, lost gift cards, etc. If you’re not experienced in manufactured spend, I highly recommend you tread lightly here and do more researching/reading before going after this. For example, what happens if you buy a $500 gift card and get home from the store and it has a $0 balance? You’d want to know the answer to questions like that before you spent $30K.
Technique #3: DCU and Plastiq
Ultimately, I settled on a third method I hadn’t considered initially.
I’ve long known that Digital Federal Credit Union (DCU) offers cheap auto loans. At the time of writing, they offer a best rate of 2.49% interest for up to 65 months whether you’re buying new or used.
Side note: Digital Federal Credit Union sounds like something I just made up with a few hip Silicon Valley venture capitalist friends. It’s not — DCU started in 1979 as a credit union serving workers of a company called Digital Equipment Corporation. These days, branches are all located in Massachusetts and New Hampshire, though anyone can join by making a $10 donation to an affiliate organization.
Rates have actually gone up a bit. When we purchased in January, the rate was 2.24% — but even at 2.49%, that’s a very low rate (especially if you’re buying used or refinancing).
If you’re looking at that number and thinking that it’s low enough that you could use a credit card and potentially come out ahead, you’re on to something — though remember that even if you used a card that earns 3% back in the first year (like the Alliant Cashback card or a Discover IT Miles card), you wouldn’t be ahead of 2.49% APR due to compound interest.
However, it is possible to earn some miles or cash back that potentially beat the cost of interest with Plastiq.
Those unfamiliar with Plastiq will want to see our Complete Guide to Plastiq credit card payments. In a nutshell: you can pay Plastiq with a credit card and they’ll send a check to a company on your behalf. Plastiq charges a 2.5% fee for credit card payments.
Plastiq also runs a pretty generous referral program. For every person you refer who pays $500 in bills through Plastiq, you’ll earn $1,000 in “fee-free dollars” (i.e. one thousand dollars of credit card payments where you will not be charged the 2.5% fee). After your friend has made $500 in payments through Plastiq, he or she will earn $500 in fee-free dollars as well. If he or she makes exactly $500 in credit card payments at 2.5% and $500 in fee-free payments, that comes to a net cost of 1.25% on $1,000 in payments. That’s not a bad deal for $1K in spend. In fact, if you have friends who will owe or want to pre-pay income taxes, it beats the rates on the official payment websites (See: Complete Guide to paying taxes with a credit card). I’m not positive that making a debit card payment for the first $500 would trigger the referral bonus — but debit card payments only carry a 1% fee, which would drop the net fee for the first $1K to just 0.5% if that works. Note that Visa and Mastercard gift cards do not run as debit trough Plastiq.
I happen to be in the very fortunate position of writing here at Frequent Miler, where I’ve been able to share my Plastiq referral link a few times. I’ve earned enough fee-free dollars to pay for my car without any credit card fees. While my situation is certainly unique in that regard, I think it’s not altogether unreasonable for most people to find 5 or 10 or 15 people who might be interested in paying $1K in taxes on a credit card (split into two separate $500 payments) for a net fee of 1.25%. Paid on a simple 2% cash-back card, that’s a net win for your friend — coming out $7.50 ahead of the fee overall. Do you know 30 people who would be interested in Plastiq? Maybe, maybe not. On the flip side, perhaps you’re looking for a car that only costs $10K or $15K or $20K — you may not need to refer so many people to get the fee-free dollars you need.
For the sake of the example, let’s say that you were able to refer 30 people to Plastiq and you therefore had $30K in fee-free dollars. Could you just charge $30K on your card and have Plastiq cut a check to the dealer? Maybe. I asked Plastiq that question and didn’t get a definitive answer.
However, I decided that I didn’t want to do that. Financing through DCU would work out better.
As I mentioned before, because of compound interest, it’s not quite as simple as paying with a 3% card and coming out ahead. Using a loan calculator, we can see that if I financed $30K for 65 months at 2.49% interest, I’d pay a total of $2,099.66 in interest over the course of the loan.
The total price paid would therefore be $32,099.66 (ignoring taxes – let’s assume that’s included in the $30K price). Assuming for a moment that you could pay your monthly payment on a 3% cash back card with fee-free dollars for the full 65 months, you’d earn $963.86 cash back. That’s still a net loss of more than $1100 in interest.
Luckily, DCU allows you to pay down principal ahead of time. Note that you have to contact them to tell them that you want your additional payment to go towards principal, otherwise excess will be applied towards a future monthly payment (I learned this the hard way). If you were able to pay 34% of the $30K loan within the first month (a one-time payment of $10,200 — added at the bottom of the following image), the total interest paid over the course of the loan drops substantially:
At this point, the total interest paid would be $916.89. If you paid the full $30,916.89 on a credit card that earns 3% cash back, you’d earn $927.51 cash back. In other words, you would earn a little more cash back than the amount of interest paid.
Of course, if you don’t want to pay so much up front, you can play with that a bit — adding some to your monthly payment and taking away some from the one-time payment as it fits your situation. For example, I settled on something sort of like this — paying $8,000 immediately and an extra $106.16 per month (in order to bring the monthly payments to an even number — in this case, $600):
But of course this post is about earning miles rather than cash back. If we dial back to the advantages of the manufactured spending technique, one of them is the ability to earn multiple signup bonuses. This DCU + Plastiq method replicates that advantage while eliminating most of the risk and time consumption. Furthermore, it enabled us to get a car now and work on signup bonuses later. And best of all, we don’t need to tie up all of the capital at once. Doctor of Credit maintains a nice list of high-yield accounts. Some of those accounts earn as much as 5-6%. By not paying for the car up front, I can hang onto the cash in a high-yield account. Let’s imagine that I did as shown above — paying $8K immediately and $600 per month. After the initial $8600 paid out, I would have $21,400 left of my original $30,000. If I put that in an account that earns 3% APY and paid my $600 credit card bill every month from that account, I can use a savings withdrawal calculator to figure out how much I could earn:
As you can see, I would start with $21,400 and withdraw a total of $22,384 — a net profit of $984. That alone would be more than the interest on the loan. Of course, that’s a bit pie-in-the-sky: I’d lose some of that interest in taxes, most of those high-yield accounts have some hoops I’d need to jump through and minimum balances, so I might not be able to get 3% all the way. On the other hand, I could take advantage of checking and savings account signup bonuses by moving that money to meet balance needs.
The key point for me is that financing the car and paying it slowly gives me a lot of advantages over manufactured spending:
- It’s less risky
- I can still earn a number of signup bonuses — both credit card and bank account
- My money is not immediately tied up in gift cards / money orders / the car
- Very little risk of shut down over Plastiq payments
Of course, there are a number of other considerations. The credit union requires a higher threshold of insurance than the minimum required by law if you buy the vehicle outright. In my case, I would have paid for the same amount of insurance either way — so this wasn’t a factor for me, but it may be for you.
But in the end, there is the possibility to earn a lot of miles:
- Earn big signup bonuses by being able to wait and cherry-pick the right offers, knowing we’ll have legitimate spend to meet the signup bonuses
- Earn 1.5x Ultimate Rewards on the Freedom Unlimited — could be worth greater than the return on a 3% cash back card depending on how you value and use Ultimate Rewards points
- Earn spending bonuses — like the 15K AA miles I got for spending $500 each of 3 months with an Aviator card a few months ago
Ultimately, I’ll earn roughly as many miles as I could with the manufactured spending technique, but I’ll keep more of my money for longer.
Disadvantages to DCU + Plastiq
- Can’t use Amex for car payments
- You’ll want to pay with a Mastercard the first time to dodge cash advance fees
- Plastiq can be slow in getting set up (though I’ve never had a major issue)
I’m sure there are a few other disadvantages I’m not immediately considering. However the advantages outweigh any downsides I could imagine.
These aren’t necessarily the only methods for earning miles on a car purchase. In fact, if you want to pay the dealer directly, you should just ask how much they will take. I told one dealer that I am a miles-and-points guy and would like to earn some miles on the purchase of the car. I asked how much they would accept on a credit card — their answer was $15,000. Another dealer told me they wouldn’t take more than $1K on a credit card (even after I told them that another dealer would take $15K). Luckily, I didn’t have to rely on finding a dealer who would take a card; by combining a great rate on financing with fee-free Plastiq dollars, I was able to focus on negotiating the best deal for the vehicle I wanted — while maximizing my mileage on the purchase.
